DST in Honduras, El Salvador, Guatemala, Nicaragua
by Jesper Norgaard Welen May 6, 2006

May 6, 2006

There is a flood of mutually conflicting stories on the near past/future DST changes in Honduras, El Salvador, Guatemala and Nicaragua. Here is a small bouquet of articles to consider, not that I will pretend to judge which are true or false: Change of DST in Honduras: http://ar.news.yahoo.com/060503/4/qmx7.html expected for this Sunday 7 at 0:00 Change of DST perhaps postponed in El Salvador: http://www.laprensagrafica.com/lodeldia/883.asp ... it has the interesting claim that Honduras changed the same time as Guatemala and Nicaragua. Change of DST in Guatemala: http://www.deguate.com/cgi-bin/noticias/print.pl?article=7134 claims that the return of DST will happen the 30.th. of September at 24 hours, or really 1.st. of October at 0:00. Another confirmation that Nicaragua change was at 2:00 in the morning: http://www.elnuevodiario.com.ni/2006/05/01/nacionales/18410: Por orden del presidente de la República, Enrique Bolaños, Nicaragua adelantó en sesenta minutos su hora oficial, ayer a las dos de la mañana, y así permanecerá hasta el 30 de septiembre. This means the following (my informal translation) By order of the president of the republic, Enrique Bolaños, Nicaragua advanced by sixty minutes their official time, yesterday at 2 in the morning, and will stay that way until 30.th. of september.

Honduras and El Salvador on DST too?
by Oscar van Vlijmen May 5, 2006

May 5, 2006

Reportedly (wordltimezone.com, some Spanish media) Honduras chose to follow Guatemala and will observe DST starting "la medianoche del sábado", so probably Saturday 06 May 2006, 24:00 local time. No ending date is mentioned other than "durante cuatro meses hasta septiembre" (during 4 months until September). My theory is: DST ends Saturday 02 September 2006 24:00 local time. El Salvador will follow Honduras. No serious details, no serious sources were given. I couldn't find any more reliable sources yet. Does anybody know more of this?

RE: Some modifications of China related timezone info.
by Paul Schauble May 1, 2006

I agree with the drawbacks of using the most populated city as a proxy for a time zone. In this case, what's wrong with calling the tz zone Asia/China and being done with it? ++PLS -----Original Message----- From: tz-request(a)elsie.nci.nih.gov [mailto:tz-request@elsie.nci.nih.gov] On Behalf Of Zhe Su Sent: Saturday, April 29, 2006 7:06 AM To: Paul Eggert Cc: tz(a)lecserver.nci.nih.gov Subject: Re: Some modifications of China related timezone info. Hi, And in my opinion, using the rule of using most populous location to identify each region is not a generic way for every countries. IMO, we should use different rules for different countries to fit their local circumstances. For China (or more exactly, PRC), it's apparently not suitable to use the population rule. Because the most populous location in China is Chongqing, which is belong to Sichuan province, the most populous province of China. But Chongqing is far less developed than Shanghai and Beijing, so it's far less popular than Beijing and Shanghai. So for China, I'd prefer to use the most important and popular location, Beijing, the capital of China to identify our unique timezone.
